Abstract. The paper examines general aviation (GA) pilot risk perception and decision-making via an online vignette study. GA is a high-risk area of aviation with many GA accidents considered to be the result of pilot performance rather than mechanical failure. Pilots ( n = 101) were presented with 12 go/no-go take-off decision scenarios across four risk categories (compromised performance, environment, faulty equipment, missing equipment). Scenarios depicting a missing checklist, missing sunglasses, and stress were considered less risky than illness, a faulty airspeed indicator (ASI), and a broken seatbelt. Pilots weighed their take-off decisions against mitigating factors, protective measures, and flight parameters. Situation awareness training and a focus on pre-flight planning may help to enhance flight safety within this group.

Environmental variables in a malaria geographic information system [GIS] database were analysed to discriminate between governorates at high and low risk of malaria. Only Fayoum governorate was categorized as a high risk area for malaria during the last 2 decades. Discriminant models correctly classified 96.3% of the risk categories and indicated that the most important predictor of risk is hydrogeology. Further GIS spatial analysis indicated that the high malaria risk in Fayoum is associated with a unique environmental envelope of biotic [presence of both efficient malaria vectors] and abiotic [hydrogeology and soil] variables. Recommendations for surveillance and control are discussed.

While the majority of research on the topic of situation awareness has been focused on designing better systems, significant interest also exists in finding ways to improve SA through training. This paper describes an ongoing program that is directed at developing programs for training SA in general aviation pilots. Factors that have been found to pose problems for SA in pilots are reviewed and directions are established for creating programs for improving SA through training.

Research exploring new technology integration into general aviation (GA) cockpits is lacking, especially that which focuses on the capabilities and limitations of the single pilot. Sixteen visual flight rules (VFR) rated pilots were evaluated for data link communication performance using a flight simulator equipped with a mixed-modality simulated data link within one of two flight conditions. Modalities included textual, synthesized speech, digitized speech, and synthesized speech/textual combination. Flight conditions included VFR (unlimited ceiling, visibility) or marginal VFR (MVFR) flight conditions (clouds 2800 feet, threemile visibility). Evaluation focused on the time required accessing, understanding, and executing data link commands. Measures to evaluate workload, situation awareness, and subjective preference were also obtained. Results indicated performance, mental workload, and situation awareness differences across data link modalities and between flight conditions. Implications for operational safety in future systems that incorporate data link for use by a single pilot are discussed.

Abstract. Identifying pilot attributes associated with risk is important, especially in general aviation where pilot error is implicated in most accidents. This research examined the relationship of pilot age, expertise, and cognitive functioning to deviations from an ideal circuit trajectory. In all, 54 pilots, of varying age, flew a Cessna 172 simulator. Cognitive measures were obtained using the CogScreen-AE ( Kay, 1995 ). Older age and lower levels of expertise and cognitive functioning were associated with significantly greater flight path deviations. The relationship between age and performance was fully mediated by a cluster of cognitive factors: speed and working memory, visual attention, and cognitive flexibility. These findings add to the literature showing that age-related changes in cognition may impact pilot performance.

Nowadays, restoration project might lead to increased public engagement and enthusiasm for biodiversity and is receiving increased media attention in major newspapers, TED talks and the scientific literature. However, empirical research on restoration project is rare, fragmented, and geographically biased and long-term studies that monitor indirect and unexpected effects are needed to support future management decisions especially in the Neotropical area. Changes in animal population dynamics and community composition following species (re)introduction may have unanticipated consequences for a variety of downstream ecosystem processes, including food web structure, predator-prey systems and infectious disease transmission. Recently, an unprecedented study in Brazil showed changes in vampire bat feeding following a rewilding project and further transformed the land-bridge island into a high-risk area for rabies transmission. Due the lessons learned from ongoing project, we present a novel approach on how to anticipate, monitor, and mitigate the vampire bats and rabies in rewilding projects. We pinpoint a series of precautions and the need for long-term monitoring of vampire bats and rabies responses to rewilding projects and highlighted the importance of multidisciplinary teams of scientist and managers focusing on prevention educational program of rabies risk transmitted by bats. In addition, monitoring the relative abundance of vampire bats, considering reproductive control by sterilization and oral vaccines that autonomously transfer among bats would reduce the probability, size and duration of rabies outbreaks. The rewilding assessment framework presented here responds to calls to better integrate the science and practice of rewilding and also could be used for long-term studying of bat-transmitted pathogen in the Neotropical area as the region is considered a geographic hotspots of “missing bat zoonoses”.
